What Is Slippage in Crypto Trading?
Slippage represents the difference between a trader's expected price and the actual execution price. This occurs due to:
- Market volatility during transaction processing
- Low liquidity in trading pairs
- Rapid price movements
Most DEXs allow you to set a slippage tolerance (typically 0.5%-3%) to manage this risk.
